Electrical Grounding and Related Topics
A grounding system analysis or study is the evaluation of the grounding system in meeting its design objectives. In the power industry, the primary focus is addressing the aspect of personnel and public safety. IEEE Std 80 provides guidance for safety related to grounding in AC substations. This standard highlights the dangerous conditions that may occur during a ground fault that can severely or fatally injure individuals in the area or in contact with metallic objects.

XGSLab GSA FD Tutorial - A Grounding System Analysis Applying IEEE Std 80
This video follows the XGSLab tutorial documentation for the GSA_FD module incorporating the IEEE Std 80-2013. In the tutorial, a substation grounding system is subjected to a fault and transfers the ground/earth potential rise to the connected steel factory grounding system. In the video we use the Soil Resistivity Analyzer to determine a soil model from Wenner resistivity measurements, then proceed to import our grounding systems for the substation, steel factory, and adjacent site entrance from an existing DXF. The fault current split tool is used to quickly determine fault split calculation, reducing the total fault contributing to the ground/earth ... Watch Video

Soil Modeling and Soil Resistivity Interpretation
Soil modeling is an important step in the analysis of grounding systems as the soil affects the system impedance and the safety criteria used to assess grounding performance. Developing a soil model can be a simple task, given quality measurements and advanced tools, like Soil Resistivity Analyzer (SRA), to aid in interpretation of the measurements. Even with advanced tools, many measurements need more engineering judgment to make an adequate interpretation of the soil measurements. The goal is to develop an accurate soil model that provides an efficient grounding design to meet the tolerable voltage limits. This article focuses on the interpretation of soil resistivity measurements to determine a soil model and is a resource for engineers designing and analyzing grounding systems.
Soil Resistivity Data
As discussed in the Soil Resistivity and Field Testing article, those analyzing grounding systems are primarily concerned with the soil resistivity typically expressed in Ω-m. Soil resistivity measurements at several locations ... Read the full article
